I wonder when someone is going to start making receivers with a higher amperage connector "such as a Deans" built in for the bigger planes.

You mean like the Spektrum and JR powersafe RX's that have been around for a while...I use them in ALL of my big planes..they work really well.....HIGH-current leads that pull from the higher voltage pack, redundant in case of a battery failure.

yup, but it's not all that hard to do if you're comfy enough with a little soldering... just need to solder a better pigtail into the servo bus. I did this with one of my receivers...

...servo bus are usually pins that are easy to solder to, put a hole through the Rx case big enough to get the wires through, solder them to the servo bus and you're good to go. I also bolstered the servo bus with a little extra wire, but not really needed.

Have to say I'd never seen those before, very nice.
Does Futaba do any like that?

i think tominator06 has a 71 on 10S with a motrolfly....has vids in the huckers thread...

Yeah I run 5s 3300mah in my 10s setup. I have a 5320-230kv now. I started with 200kv but needed a 22" prop to get the power I needed. Ken said that motor should be fine on 10a with a18-19" prop or I could rewind. I opted for the rewind. Bigt4471 is my YouTube channel name if you want some vids.
